Quantitative metabolomic and lipidomic profiling reveals aberrant amino acid metabolism in type 2 diabetes
(
Royal Society of Chemistry
, 2013 , Article)
Type 2 diabetes (T2DM) is a multi-factorial disease with a complex pathogenic mechanism; however a complete understanding of precise biochemical alterations accompanying the onset and progression of T2DM is lacking. Using ...
The predictive value of IL28B rs12979860, rs11881222 and rs8099917 polymorphisms and IP-10 in the therapeutic response of Egyptian genotype 4 patients
(
Elsevier
, 2013 , Article)
Interleukin-28B (IL28B) polymorphisms have previously been reported to be strongly associated with spontaneous and treatment-induced HCV viral clearance. AimTo assess the impact of four different IL28B polymorphisms and ...
Association of adiponectin gene polymorphism (+T45G) with acute coronary syndrome and circulating adiponectin levels
(
SAGE
, 2012 , Article)
We investigated the association of adiponectin gene polymorphisms (+T45G and +G276T) and adiponectin levels with acute coronary syndrome (ACS) among Arabs in Qatar. A case-control study was performed in 142 Arab patients ...
Genetic polymorphisms of ICAM 1 and IL28 as predictors of liver fibrosis severity and viral clearance in hepatitis C genotype 4
(
Elsevier
, 2013 , Article)
Background and objectivesIntercellular adhesion molecule-1 (ICAM-1) is located on chromosome 19p13.2, and this protein plays an important role in the pathogenesis of the hepatitis C virus (HCV). The rs12979860 polymorphism ...
Significant association of close homologue of L1 gene polymorphism rs2272522 with schizophrenia in Qatar
(
Wiley Online Library
, 2012 , Article)
Introduction: Previous reports have found that polymorphisms in the close homologue of L1 (CHL1) gene located on chromosome 3p26 are associated with schizophrenia among different ethnic populations. The aim of this study ...
Sensorless sliding mode observer for a five-phase permanent magnet synchronous motor drive
(
Elsevier
, 2015 , Article)
This paper deals with the sensorless vector controlled five-phase permanent magnet synchronous motor (PMSM) drive based on a sliding mode observer (SMO). The observer is designed considering the back electromotive force ...
Modelling and analysis of a three-phase to five-phase transformer
(
Walter de Gruyter GmbH
, 2014 , Article)
Multi-phase systems are the focus of research in recent times due to their inherent advantages compared to the three-phase counterpart. A lot of research effort has been put to develop commercially feasible multi-phase ...
Common-mode voltage and vibration mitigation of a five-phase three-level NPC inverter-fed induction motor drive system
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Common-mode (CM) voltage is one of the main reasons for the flow of bearing currents in induction motors (IM) that ultimately leads to the bearing failure and causes severe vibrations. For three-phase IM drives, many works ...
Post fault operation of a dual matrix converter fed open-end load
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the fault tolerant control strategies for a three to five-phase dual matrix converter fed open-end load system. There are two three to five phase matrix converter at both the ends of the load. In ...
Modelling and implementation of SVPWM technique for a fifteen-phase voltage source inverter for sinusoidal output waveform
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper space vector model of a fifteen-phase voltage source inverter (VSI) is presented. The space vector Pulse Width Modulation (SVPWM) of a fifteen-phase voltage source inverter (VSI) with the aim of producing ...
